Hey guys, on the new project want to make sure that whatever I do is with mind to going to the track later. the bucket seat that is in the car now doesn't look like provision for harness. was thinking of replacing with something like this:

My concern is, I'm a big guy, my uncle who will also drive it is even bigger (he's 325lbs), I don't usually like seats that come in on the sides like this, feel cramped. are there other options that aren't super pricey? (cheaper than this would be even better )

Also, harness, is something like this the way to go?

Looks like that one I can just put around the bar in the roll cage that's crosses below shoulder level. do harnesses come in different sizes, or will this fit somebody my uncles size?

Muchisimas Gracias companeros.
